Previously we always loaded all the svg files using the raw-loader
which fetches the entire svg body to add it inline inside an our HTML.
This a very flexible way to load them that has the advantage of allowing our client side code to manipulate the SVGs (such as adding styles).

However, this requires us to use v-safe-html to place the SVG inside
our markup, and makes SVG images work differently from other like PNG
and JPG.

This MR has our SVGs loaded as before by default, but allows us to
opt-in by adding a ?path query at the end of the import so it can be
loaded as any old image.
